A series of α, ω-bis-(p-aminophenoxy)-alkanes were found to show schistosomicidal activity against experimental animals, but having toxic effect. Based upon the fundamental chemical skeleton, we designed the following type: to study the relationship between their chemical constitution and schistosomicidal activity. N, N'-bis-(p-substituted phenyl)-α,ω-polymethylenediamines were prepared by the condensation of the sodium salts of p-substituted p-toluenesulfonanilides with α, ω-dibromoalkanes, followed by hydrolysis with hydrobromic acid and phenol. But the two bromo compounds were obtained by hydrolysis with hydrochloric acid, since treatment with hydrobromic acid possibly resulted in the loss of the nuclear bromine atoms. Among this series, N, N'-bis-(p-halo-phenyl)-α, ω-heptanediamine were also prepared by the direct condensation of the corresponding p-substituted anilines with α, ω- dibromoheptane in alcoholic solution.

α,ω-双-[对-氨基苯氧基]-烷类化合物对感染日本血吸虫病实驗动物有作用,但毒性較高,经改变其結构,将氨基移至苯核內侧,对位用甲基,卤素或硝基替代,成N,N′-双-(对-取代苯基)-α,ω-烷二胺类化合物,以察其化学結构和疗效的关系。 N,N′-双-(对-取代苯基)-α,ω-烷二胺类化合物由对-甲苯磺酰对-取代苯胺,氫氧化鈉和α,ω-二溴烷类在乙醇中縮合成N,N′-双-(对-甲苯磺酰)-N,N′-双-(对-取代苯基)-α,ω-烷二胺,然后用氫溴酸和苯酚进行水解而得,其中溴代化合物水解时核上溴原子可能脫落,所以用盐酸水解之。此类化合物中N,N′-双-(对-氯苯基)-α,ω-庚二胺和N,N′-双-(对-溴苯基)-α,ω-庚二胺另由相应的对-取代苯胺和-α,ω-二溴烷类及碳酸氫鈉在乙醇中縮合制备。

In toluene, the π-molecular orbital complex (ClB·N·C_6H_4·Br-p)_3.·1/2C_6H_5CH_3 was prepared from boron trichloride and p-bromoaniline by one-step reaction. In chloro benzene, only (CIB.N.C_6H_4.Br-p)_3 was obtained. A tentative explanation was sug gested.

在甲苯中可以从三氯化硼及对溴苯胺一步合成(C1B·N·C_6H_4·Br-P)_3,产品含半分子甲苯(Ⅰ)。若改用氯苯作溶剂,則得不含溶剂的产品(Ⅱ)。本文并研究合成条件对产率的影响,找出加入三乙胺不能提高产率。B-苯基衍生物的粗产物易自氧化而遭破坏,但相应的脂肪烴基衍生物則較稳定。仲丁基衍生物的得率可采用在乙醚中长期回流的方法而提高。在本实驗中合成六种(RB·N·C_6H_4·Br-P)_3(R=C_6H_5,CH_3,n-C_4H_9,i-C_4H_9,sec-C_4H_9,CH_2=CHCH_2)型化合物。(CH_3B·N·C_6H_4·Br-p)_3的产率为56%。据初步实驗的結果表明B-三烯丙基-N-三对溴苯基硼氮六环不易自行聚合。

The colour reactions of titanium with eight 9-substituted-2, 3, 7-trihydroxyfluorones(methyl-,phenyl-,p-bromophenyl-,p-dimethylaminophenyl-, m-nitrophenyl-,o-nitrophenyl-,salicyl-and β-hydroxynaphthyl-)in the presence of cationic surfactant have been investigated. It is shown that in a solution of 0.1—0.35N sulfuric acid titanium can form a complex with o-nitrophenylfluorone and CTMAB in red-purple colour exhibiting maximum absorption at 542nm. The value of molar absorption coefficient is 2.10×10~5. The constituent...

The colour reactions of titanium with eight 9-substituted-2, 3, 7-trihydroxyfluorones(methyl-,phenyl-,p-bromophenyl-,p-dimethylaminophenyl-, m-nitrophenyl-,o-nitrophenyl-,salicyl-and β-hydroxynaphthyl-)in the presence of cationic surfactant have been investigated. It is shown that in a solution of 0.1—0.35N sulfuric acid titanium can form a complex with o-nitrophenylfluorone and CTMAB in red-purple colour exhibiting maximum absorption at 542nm. The value of molar absorption coefficient is 2.10×10~5. The constituent of the complex is established by methods of isomolar continuous variation and equilibration shift as Ti:o-NPF:CTMAB=1:4:4. The reaction is highly selectitve and sensitive to titanium ions. Many other metals don't give similar reactions except niobium and tantalum. A spectrophotometric method for the determination of titanium in steel alloys and aluminium metal has been developed, and the satisfactory results were obtained.

本文研究了八种2,3,7-三羟基萤光酮-9-取代物(甲基、苯基、对-溴苯基-、对-二甲氨基-、间硝基苯基、对硝基苯基、水杨基以及β-羟基萘基)在阳离子表面活性剂存在下与钛的胶束增敏显色反应,结果发现,邻硝基苯基萤光酮与溴化十六烷基三甲基铵在0.1—0.35N的硫酸介质中,可以与钛形成灵敏度极高的红紫色络合物,其最大吸收峰位于542nm。络合物的表观摩尔吸光系数ε_(542)为2.10×10~5,为目前钛的显色反应中灵敏度最高的络合物,方法选择性良好,除铌与钽以外,其它金属阳离子均不影响钛的测定。利用上述显色反应,拟定了各种合金钢及纯铝中微量钛的分光光度测定法,并取得了令人满意的结果。
